New advances in solar energy in thin film
The solar producers weigh their costs in terms of dollars per watt of energy produced, a formula that is a combination of the cost of producing a module and its energy efficiency.
At present the best products crystalline silicon modules can sell from $ 3 to $ 4 per watt, First Solar can sell at around of $ 2.40 per watt, a price the company expects to reduce soon. “I really have pushed the company the threshold. Said Travis Bradford, author of Solar. “They have great technology”
But First Solar does not generate the most Sumba. That notoriety belongs to venture Nanosolar, which shockeo its competitors in December when it announced that it would be profitable to sell thin-film panels at $ 1 watt. This figure is the Holy Grail sun, the point at which the solar energy is generally less expensive than coal, without the help of subsidies.
The senior manager Martin Roscheisen Nanosolar, who, like many solar kings, has roots in Silicon Valley, says he can achieve radical cost savings by directly applying an ink composed of nanoparticles. Nanosolar cells Powersheets of machines as they roll in pages of newspapers in print, on an average of several hundred feet per minute. Roscheisen, a strong Austrian says the first 18 months of production Nanosolar have already been purchased. “We share the market by 35% in the coming years,” he said. “The truth is that we can climb a lot more products for less.
Roscheisen’s competitors, to put it in a gentle way, they doubt his claims, noting that with the cost of raw material cost would be impossible to produce panels at $ 1 per watt. “Of course I doubt,” he said. “Otherwise, their model would be a joke.”
